“…The slow-wave concept was then extended to more complex structures such as the Coupled Slow-wave CoPlanar Waveguides (CS-CPWs) [36]. To derive the electrical model of these complex structures, the capacitance calculation methodology presented in [35] was merged together with the resistance and inductance calculation proposed in [37], leading to a completely parametrical model for CS-CPWs [38].

“…In this article, authors presented the CS-CPW topology and gave broad design rules. Subsequently, an analytical parametric model was given in [15] together with the design and experimental validation of state-of-the-art mm-wave 3-dB couplers. Indeed, couplers presented in [15] reported the greatest RBW in terms of insertion loss and phase difference as well as a great isolation.…”

This paper presents an innovative Through-Load element aimed at characterization applications at mm-wave frequencies. The proposed structure can behave as a Through connection or as a 50-Ω load depending on a DC control voltage. Among other potential applications, this system can be used to implement a transfer switch or an attenuator. A demonstrator was fabricated and measured in the STM 55-nm BiCMOS technology. Over a wide bandwidth, from 55 GHz up to 170 GHz, experimental measurements demonstrate a maximum 1.6-dB of insertion loss when behaving as a Through connection and a minimum 14-dB of insertion loss when behaving as a 50-Ω load. In both cases, the return loss is better than 10 dB. The insertion loss at 90 GHz is 0.6 dB for the Through connection and 20 dB for the 50-Ω load connection.

“…5, was first presented in [11]. Then, a complete parametric model was proposed together with two demonstrators, showing the capabilities of this architecture [12]. Thanks to the slow-wave effect, firstly presented in [13] for CPWs, this architecture presents a reduced footprint, as compared to traditional coupled CPWs.…”

This paper presents an innovative architecture for the implementation of an Electrostatic Discharge (ESD) protection for mm-wave devices. The proposed architecture is based on the use of 3-dB couplers, whose coupled outputs have been shorted to the ground node. In order to reduce the physical dimensions of the 3-dB coupler and to reach the high coupling required for this application, the Coupled Slow-wave CoPlanar Waveguides (CS-CPW) architecture was favored. The demonstrator of the proposed system was fabricated in the ST Microelectronics 55-nm BiCMOS technology, demonstrating a return loss greater than 10 dB across the 50 to 160 GHz frequency range, an attenuation greater than 18 dB below 5 GHz and a minimum insertion loss at 90 GHz of 0.55 dB. To prove the performance of the proposed solution, HBM and CDM events were simulated at the input of the 3-dB coupler, showing that the proposed architecture effectively protects against these events while minimally impacting the RF path.
